<p>How would one go about testing the <code>init()</code> function in the following example?</p>
<pre><code>package prj
import (
"log"
"os"
)
const workRootEnvVar = "$WORK_ROOT"
func init() {
//get $WORK_ROOT env var
rootPath := os.ExpandEnv(workRootEnvVar)
if rootPath == "" {
log.Fatalln("%s must be defined.", workRootEnvVar)
}
}
</code></pre>
<hr/>**评论：**<br/><br/>Luett_un_Luett: <pre><p>You do not test init(). You test the package interface. If init() fails your public interface will fail or else there is no need for init() anyway</p></pre>
